How do I align equations on the equals sign? (Where are the old MacOS versions of LO?)

[Ben23]

I have the following issues with libremath:
I want to continue an equation on the line below and start with an equals sign which I want aligned below the equals sign above. I have followed the recommended method of entering empty braces before the equals but it just shows the empty braces above in the finished formula & aligns the equation to the left?

Fonts - I only have the option of one text font?

I am able to use libreoffice version 5 with my PC but I can’t use libreoffice with mac os x 10.6.8, is there a version I can use with this or os x 10.7?
If not what is the oldest version of os x that is supported?

Perhaps use the matrix { } function? Example on the AOO wiki here.

It is incredibly difficult to find this information. I’m not certain why it is not documented more clearly nor explicitly.

In general for Macs:

• The current (March 2016, version-5) system requirements for Macs are:-

• Mac OS X 10.8 (Mountain Lion) or higher
• intel cpu

• compatibility for earlier mac versions is shown on the Wiki Gatekeeper page:-

• Mac_10.4/10.5:- v4.0.x (max is 4.0.6.2, x86 or ppc)
• Mac_10.6 - 10.7.4:- v4.1.x (4.1.6.2, x86 only), v4.2.x (4.2.8.2, x86 or x64), v4.3.x (4.3.7.2, x86 or x64)
• Mac_10.7.5:- v4.2.x (4.2.8.2, x86 or x64), v4.3.x (4.3.7.2, x86 or x64)
  
  [requires Gatekeeper to be set to “Identified Developers” or lower during installation]

Detailed Release Information is here (does NOT cover system requirements).
